Some Improvement Seen in Cognitive Function With Exercise, Ibuprofen in Cancer
In continution of my update on Ibuprofen
For adults with cancer receiving chemotherapy, an exercise intervention and low-dose ibuprofen improved some domains of cognitive function, according to a study published online April 20 in Cancer.
Michelle C. Janelsins, Ph.D., M.P.H., from the University of Rochester in New York, and colleagues randomly assigned 86 adult participants with cancer receiving chemotherapy and reporting cognitive problems to one of four study arms for six weeks: Exercise for Cancer Patients (EXCAP)-ibuprofen, EXCAP-placebo, ibuprofen only, and placebo only. EXCAP is a home-based, low- to moderate-intensity progressive walking and resistance exercise prescription.
The researchers found that compared with the placebo group, participants in the EXCAP-placebo group had significantly better attention performance on the Trail Making Test (–21.57 seconds). Greater improvements were seen for the ibuprofen-only group versus the placebo group (difference of –11.27 seconds). Improvements on the Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog) "comments from others" subscale were exhibited by participants in both the EXCAP-ibuprofen and EXCAP-placebo groups compared with the placebo group. Participants in the EXCAP-placebo group had a significant improvement on Rapid Visual Processing mean latency compared with the placebo group; those receiving ibuprofen had an improvement compared with those receiving placebo, which was attributed to a trend after adjustment for reading score. Compared with those not receiving ibuprofen, the ibuprofen group performed less well on the Hopkins Verbal Learning Test‐Revised delayed.
"We are encouraged by the findings of this trial that suggest possible benefits of both interventions for some cognitive domains. Clearly, we saw a more pronounced effect with exercise, which is notable considering the multiple health benefits of exercise for cancer survivors," Janelsins said in a statement.

Combining Cannabinoid With Opioid Does Not Relieve Pain in Knee Osteoarthritis
For patients with knee osteoarthritis, combining a cannabinoid medication with an opioid does not provide additional pain relief, according to a study published in the May issue of Anesthesiology.
Katrina R. Hamilton, Ph.D., from Johns Hopkins University School of Medicine in Baltimore, and colleagues examined the acute analgesic and drug effects of synthetic delta-9-tetrahydrocannabinol and hydromorphone, alone and in combination, in 21 individuals with knee osteoarthritis (mean age, 63.4 years). Participants received oral combinations of placebo, hydromorphone (2 mg), and dronabinol (10 mg).
The researchers found greater pressure pain threshold analgesia for hydromorphone than dronabinol and greater capsaicin and noncapsaicin sensitized mechanical temporal summation analgesia versus placebo. No significant drug-related differences were seen for clinical pain severity, thermal threshold or tolerance, temporal summation, cold pressor, conditioned pain modulation, capsaicin-induced thermal threshold, central sensitization, general pain sensitivity, or physical functioning (two-minute walking distance, Timed Up and Go, and total stair climb time). Compared with all conditions, hydromorphone impaired working memory accuracy and produced greater good effects than placebo in terms of secondary outcomes. Working memory reaction time was impaired with hydromorphone + dronabinol, which produced greater high ratings than placebo, greater drug effects than placebo + hydromorphone, and higher nausea than hydromorphone. Greater high ratings were seen for dronabinol than hydromorphone.
"Some patients believe combining cannabis with opioids can help with pain, and clinicians may recommend or prescribe it in states where cannabis is legal," Hamilton said in a statement. "Our study suggests that isn't the case and patients may experience more side effects when the drugs are combined."

FDA Approves Idvynso (doravirine and islatravir) for the Treatment of HIV-1 Infection in Adults
In continuation of my update on Doravirine
Merck (NYSE: MRK), known as MSD outside of the United States and Canada, announced the U.S. Food and Drug Administration (FDA) approval of Idvynso, a new, two-drug single-tablet regimen of 100 mg doravirine and 0.25 mg islatravir, for the treatment of HIV-1 infection in adults to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no history of virologic treatment failure and no known substitutions associated with resistance to doravirine. Idvynso is contraindicated when co-administered with drugs that are strong cytochrome P450 (CYP)3A enzyme inducers and lamivudine (3TC) or emtricitabine (FTC). Co-administration with these drugs may decrease the effectiveness of Idvynso. See additional selected safety information on the following pages. Idvynso (pronounced ihd-VIHN-soh) will be available in pharmacies after May 11.
Islatravir
- Idvynso is approved for adults with virologically suppressed HIV-1 with no history of virologic treatment failure and no known substitutions associated with resistance to doravirine
- Idvynso is the first and only non-INSTI, tenofovir-free, once-daily, complete two-drug regimen to demonstrate non-inferior efficacy in a head-to-head Phase 3 trial versus three-drug regimen Biktarvyi (BIC/FTC/TAF)
“Advances in HIV treatment mean more people living with HIV are living longer — a remarkable achievement,” said Carl Baloney, Jr., president and chief executive officer of AIDS United. “People aging with HIV face additional health challenges, including managing multiple chronic conditions and medications at the same time. It is essential that management of HIV considers these factors in addition to virologic suppression when choosing an HIV treatment regimen.”
“Idvynso combines islatravir, a next-generation NRTI with multiple mechanisms of action, including translocation inhibition, with doravirine, an NNRTI with an established efficacy and safety profile. As the only two-drug, non-INSTI, tenofovir-free regimen, Idvynso expands therapeutic diversity beyond the currently available oral treatment options,” said Dr. Eliav Barr, senior vice president and chief medical officer, Merck Research Laboratories. “As the health needs of adults living with HIV change over time, Idvynso gives clinicians a new choice for HIV treatment. This approval marks an important new chapter in Merck’s long-standing commitment to research and discovery for people living with HIV.”
Idvynso is a complete regimen; co-administration with other antiretroviral medications for treatment of HIV-1 infection is not recommended. Severe skin reactions, including Stevens-Johnson syndrome/toxic epidermal necrolysis, have been reported with doravirine-containing regimens. Drug Rash with Eosinophilia and Systemic Symptoms was reported with Idvynso. Concomitant use of Idvynso and certain other drugs may result in known or potentially significant drug interactions, some of which may lead to loss of therapeutic effect of Idvynso and possible development of resistance, or possible clinically significant adverse reactions from greater exposures of a component of Idvynso. See additional selected safety information on the following pages.
“Idvynso is the first non-INSTI, tenofovir-free, two-drug regimen to demonstrate non-inferior efficacy to standard oral antiretroviral regimens, including Biktarvy. This makes Idvynso a potential alternative for people with virologically suppressed HIV who may need to switch their treatment,” said Dr. Amy Colson, director of research at Community Resource Initiative, Boston, Massachusetts.
Phase 3 studies supporting approval of Idvynso
The efficacy and safety of Idvynso is supported by Week 48 data from two randomized, active-controlled, non-inferiority trials [Trial 052 (NCT05630755) and Trial 051 (NCT05631093)] in virologically-suppressed (HIV-1 RNA less than 50 copies per mL) adults living with HIV. Participants must have been stably suppressed on their baseline regimen for at least 3 months prior to trial entry and had no history of treatment failure. Across the two trials, a total of 708 participants received once-daily Idvynso; of these, 81 (11%) participants were aged 65 years and older, including 10 (1%) aged 75 years and older.
In the double-blind Trial 052, participants were switched from Biktarvy [bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF)] to Idvynso. A total of 513 participants were randomized (2:1) and were switched to once-daily Idvynso (n=342) or remained on BIC/FTC/TAF (n=171). At baseline, participants had a mean age of 48 years (range: 19 to 77), 21% of participants were female, 61% were White, 31% were Black/African American, and 6% were Asian. A total of 23% identified as Hispanic/Latino.
In the open-label Trial 051, participants were switched from an oral ART (antiretroviral therapy) regimen to Idvynso. A total of 551 participants were randomized (2:1) and were switched to once-daily Idvynso (n=366) or remained on their baseline ART (bART) (n=185). Randomization was stratified by bART. At baseline, participants had a mean age of 50 years (range: 18 to 83), 40% of participants were female, 39% were White, 45% were Black/African American, and 5% were Asian. A total of 15% identified as Hispanic/Latino. At enrollment, 64% of the participants were receiving integrase strand transfer inhibitor (INSTI)-based regimens, 5% protease inhibitor (PI)-based regimens (including combinations with INSTI), and 30% were receiving other regimens.

Experimental drug cuts Parkinson's-linked protein up to 60% in early trial
Scientists have long believed that lowering the activity of the LRRK2 protein could help slow or modify the disease, but turning that idea into a viable therapy has remained a challenge, said co-author of the study Danielle Larson, MD, '15, '18 GME, assistant professor in the Ken & Ruth Davee Department of Neurology's Division of Movement Disorders.
"This was a multicenter clinical trial looking at an antisense oligonucleotide therapy for LRRK2-specific Parkinson's disease," Larson said. "The main goal was to examine the safety of delivering this therapy to patients, with the hope that if it proved safe, future studies could evaluate whether it might slow disease progression."
The study tested whether BIIB094 could safely reduce LRRK2 levels in people with Parkinson's disease. The results suggest it can be done without serious safety concerns, Larson said.
In the randomized, placebo-controlled trial, 82 participants with Parkinson's disease were enrolled across two study segments. In the first, 40 participants received a single dose of BIIB094 or placebo. In the second, 42 participants received four doses of the drug or placebo, administered every four weeks. The therapy was delivered intrathecally: directly into the cerebrospinal fluid through a lumbar puncture.
Participants in the second section were stratified based on whether they carried a known LRRK2 genetic variant.
Across both parts of the trial, the treatment was generally well tolerated. While adverse events were common, they were mostly mild to moderate and did not limit dosing. No serious adverse events related to BIIB094 were reported, according to the study.

Immunome Announces Submission of New Drug Application to U.S. FDA for Varegacestat for the Treatment of Adults with Desmoid Tumors
Immunome, Inc. (Nasdaq: IMNM), a biotechnology company committed to developing first-in-class and best-in-class targeted cancer therapies, announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for varegacestat, an investigational, oral, once-daily gamma secretase inhibitor (GSI), for the treatment of adults with desmoid tumors.
- New Drug Application (NDA) supported by positive Phase 3 RINGSIDE results, including significant improvement in progression-free survival vs. placebo (hazard ratio = 0.16, p<0.0001)
- Trial also met all key secondary endpoints, with varegacestat delivering an objective response rate of 56%
- Detailed Phase 3 RINGSIDE data selected for oral presentation at the 2026 ASCO Annual Meeting
“The varegacestat NDA submission marks an important milestone for Immunome. It reflects the strength of the RINGSIDE dataset and the commitment of the team advancing this program,” said Clay B. Siegall, Ph.D., President and Chief Executive Officer of Immunome. “We believe varegacestat has the potential to provide adults with progressing desmoid tumors with a meaningful new oral treatment option, and we are grateful to the patients, families, investigators and study site teams whose participation made this submission possible.”
The NDA is supported by positive results from the global, randomized, double-blind, placebo-controlled Phase 3 RINGSIDE trial of varegacestat in patients with progressing desmoid tumors.
The trial met its primary endpoint of improving progression-free survival, demonstrating a statistically significant and clinically meaningful improvement vs. placebo, with an 84% reduction in the risk of disease progression or death (hazard ratio (HR) = 0.16, 95% CI: 0.071, 0.375; p<0.0001). The confirmed objective response rate (ORR) based on RECIST v1.1 was 56% with varegacestat vs. 9% with placebo (p<0.0001), as assessed by blinded independent central review.
In an exploratory analysis, varegacestat demonstrated a median best change in tumor volume of -83% vs. +11% with placebo, as assessed by blinded independent central review. In addition, the trial met all key secondary endpoints, with varegacestat achieving statistically significant improvements vs. placebo in landmark tumor volume reduction and worst pain intensity.
Varegacestat was generally well tolerated, with a manageable safety profile consistent with the GSI class. The most common adverse events for participants in the treatment arm were diarrhea (82%), fatigue (44%), rash (43%), nausea (35%) and cough (34%). Most events were grade 1 or 2.
Immunome previously announced that data from RINGSIDE has been selected for presentation in an oral abstract session at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting, taking place May 29-June 2, 2026 in Chicago.
About the RINGSIDE Trial
The global, randomized, double-blind, placebo-controlled Phase 3 RINGSIDE trial (NCT04871282) evaluated the efficacy and safety of varegacestat in patients with progressing desmoid tumors. A total of 156 patients were randomized to receive varegacestat 1.2 mg daily or placebo until disease progression or death, representing the largest randomized study in this population. The primary endpoint of the trial was progression-free survival as assessed by blinded independent central review. Statistically controlled secondary endpoints were confirmed ORR using RECIST v1.1 and change in tumor volume at week 24, both determined by blinded independent central review, as well as change in pain intensity at week 12 as determined using a patient reported outcome instrument. Additional secondary endpoints included duration of response, best reduction in tumor volume, patient-reported outcomes, and safety and tolerability. RINGSIDE includes an open-label extension phase, which is ongoing.
About Desmoid Tumors
Desmoid tumors (also known as aggressive fibromatosis or desmoid-type fibromatosis) are aggressive non-metastatic soft tissue tumors that are prone to recurrence. Approximately 1,000-1,650 people are diagnosed with desmoid tumors each year in the United States, and there are approximately 10,000-11,000 actively managed patients. Those affected face debilitating pain, deformity and, in some cases, life-threatening organ damage. The chronic pain and physical limitations associated with desmoid tumors lead to a high clinical burden and impaired quality of life. Although desmoid tumors are not considered cancerous, they often require systemic treatment to prevent permanent disability and alleviate disease burden.
About Varegacestat
Varegacestat (formerly AL102) is an investigational, oral, once-daily gamma secretase inhibitor. In December 2025, Immunome reported positive topline results for the Phase 3 RINGSIDE trial of varegacestat in adults with progressing desmoid tumors. Data from RINGSIDE have been selected for oral presentation at the 2026 ASCO Annual Meeting.

New drug combination doubles down on Alzheimer's treatments
Individuals with Alzheimer's have a buildup of toxic amyloid proteins in the brain. Researchers from the School of Pharmacy at the University of Waterloo combined amyloid-destroying small molecules with anti-amyloid antibodies that are already used in Alzheimer's treatment. They found that it neutralized the clumping of proteins that accumulate in the brain, leading to better outcomes.
Alzheimer's is the major cause of dementia. Dementia affects nearly 750,000 people in Canada, with a million cases expected by 2030. Alzheimer's has no cure and current medications only relieve a patient's symptoms. Anti-amyloid antibody therapies on their own can slow the disease, but they also come with risks that can be fatal, including brain swelling and bleeding.
"We already know the small molecules resveratrol or curcumin, which are found in some common foods, block the buildup of amyloid," said Dr. Praveen Nekkar Rao, a professor in the School of Pharmacy at Waterloo. "What's new and exciting is our combination of these molecules with the anti-amyloid antibodies. This approach could allow clinicians to use lower doses of antibodies, potentially reducing the risk of serious treatment-related side effects."
Since there are few effective treatments for Alzheimer's, researchers at Waterloo studied whether using two treatments together could work better than using just one. They chose resveratrol and curcumin because they are natural compounds known to reduce amyloid buildup and inflammation.
"I was inspired by chemotherapy, which involves taking multiple medications for effective treatment," Nekkar Rao said. "Alzheimer's is a complex disease, but there are very few combination therapy approaches. Our results show that the way forward is definitely combination therapy."
The researchers emphasize that the study does not suggest that people should start consuming resveratrol or curcumin to prevent or treat dementia. You would have to consume an unsafe amount in order to reach the brain. The next phase of the research will focus on designing next-generation drugs that can reach the brain more effectively, interact favorably with amyloids and pair seamlessly with antibody treatments.

FDA Approves Revtorpyk (gedatolisib) for the Treatment of HR+/HER2-, PIK3CA Wild-Type Locally Advanced or Metastatic Breast Cancer
Celcuity Inc. (Nasdaq: CELC), a biotechnology company focused on developing and commercializing targeted therapies for multiple solid tumor indications, announced the U.S. Food and Drug Administration (“FDA”) approval of Revtorpyk (gedatolisib) for the treatment of patients with hormone receptor positive (“HR+”), human epidermal growth factor receptor 2 negative (“HER2-”), locally advanced or metastatic breast cancer without a PIK3CA mutation detected following progression on or after treatment with at least one line of endocrine therapy in the metastatic setting. Revtorpyk is the only inhibitor of class I PI3K isoforms (α, β, δ, γ) and mTOR complexes mTORC1 and mTORC2 to receive FDA approval.
- Revtorpyk is the first and only FDA-approved therapy that inhibits all class I PI3K isoforms (α, β, δ, γ) and mTOR complexes mTORC1 and mTORC2
- In the Phase 3 VIKTORIA-1 trial, Revtorpyk combined with palbociclib and fulvestrant and Revtorpyk combined with fulvestrant reduced the risk of disease progression or death by 76% and 67%, respectively, compared to fulvestrant among patients with PIK3CA wild-type advanced or metastatic breast cancer
“The PI3K/AKT/mTOR, or PAM, pathway is one of the most important targets in cancer, but comprehensively inhibiting it has stymied researchers and drug developers for nearly two decades,” said Brian Sullivan, CEO and co-founder of Celcuity. “Revtorpyk addressed this 20-year challenge by becoming the first pan-PI3K, mTORC1/2 inhibitor approved by the FDA. We are thankful for the opportunity to make this important new therapy available to patients with HR+/HER2- locally advanced or metastatic breast cancer.”
HR+/HER2- breast cancer is the most common subtype of breast cancer, accounting for approximately 70% of all breast cancers.1 Among this breast cancer subtype, approximately 60% have PIK3CA wild-type disease.2
“For patients with HR+/HER2- locally advanced or metastatic breast cancer, there is an urgent need for new treatment options that can meaningfully increase the likelihood of survival without disease progression or death,” said Sara Hurvitz, MD, Senior Vice President, Clinical Research Division, Fred Hutchinson Cancer Center, Smith Family Endowed Chair in Women’s Health and Professor and Head, Division of Hematology and Oncology, University of Washington, School of Medicine and co-principal investigator for the VIKTORIA-1 trial. “With the approval of Revtorpyk, oncologists now have an effective new treatment option for these patients.”
The approval of Revtorpyk is based on positive clinical results from the PIK3CA wild-type cohort of the Phase 3 VIKTORIA-1 trial, an open-label, global, randomized clinical trial evaluating the efficacy and safety of Revtorpyk plus fulvestrant, with or without palbociclib, for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 therapy and an aromatase inhibitor. In the VIKTORIA-1 trial, median progression free survival (“PFS”) with the Revtorpyk triplet (Revtorpyk plus palbociclib and fulvestrant) was 9.3 months versus 2.0 months with fulvestrant, an incremental improvement of 7.3 months (HR=0.24; 95% CI: 0.17-0.35; p<0.0001). The objective response rate (“ORR”) of the Revtorpyk triplet was 32% compared to 1% with fulvestrant and the median duration of response (“DOR”) was 17.5 months. For the Revtorpyk doublet (Revtorpyk plus fulvestrant), the median PFS was 7.4 months versus 2.0 months with fulvestrant, an incremental improvement of 5.4 months (HR=0.33; 95% CI: 0.24-0.48; p<0.0001). The ORR of the Revtorpyk doublet was 28% and the median DOR was 12.0 months. The median DOR was not determinable for fulvestrant because there was only one objective response.
“Today’s approval of Revtorpyk addresses a significant unmet need for the thousands of patients affected each year by HR+/HER2-, PIK3CA wild-type locally advanced or metastatic breast cancer whose disease has progressed after endocrine therapy,” said Igor Gorbatchevsky, MD, Chief Medical Officer of Celcuity. “We are deeply grateful to the patients and their caregivers, investigators and clinical study teams, and Celcuity team members who made this advancement possible.”
Celcuity anticipates commercial launch in late Q3 2026. Based on the company’s commitment to ensuring broad, affordable, and unrestricted patient access to Revtorpyk, we have designed a comprehensive patient support program. To make Revtorpyk available to patients prior to commercial launch, those who are eligible will be able to enroll in Celcuity’s expanded access program.
Celcuity plans to submit in Q3 2026 a supplemental New Drug Application (“sNDA”) to the FDA for Revtorpyk for the treatment of HR+/HER2-, PIK3CA mutated, locally advanced or metastatic breast cancer, following at least one line of endocrine therapy based on results from the mutant cohort of the Phase 3 VIKTORIA-1 trial. Results for this study were recently presented in a late-breaking abstract oral session at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting. Following the sNDA submission, Celcuity intends to submit VIKTORIA-1 data for marketing authorization of gedatolisib to other regulatory authorities around the world.
Revtorpyk is also being studied in the ongoing Phase 3 VIKTORIA-2 clinical trial incorporating two independent studies evaluating two separate patient cohorts with HR+/HER2- locally advanced or metastatic breast cancer who are treatment-naive in the advanced setting.
Revtorpyk is in development for the first-line treatment of HR+/HER2- locally advanced or metastatic breast cancer and for the second-line treatment of metastatic castration resistant prostate cancer.
